Ticket Name: TDA2SG: TDA2_Crash_PVR_K_and_Kerne

Query Text:
Part Number: TDA2SG Other Parts Discussed in Thread: TDA2 Hi Sir: Our company has a TDA2 product. Now the system will crash. The attachment is the log when the crash. Is there any direction to solve the problem? The product in this problem has the function of using MLO to perform DDR tests. There is no problem with the DDR test at present. The same firmware does not have this problem with other hardware. Is there any way to test MMU units? 0880.Crash_Log.txt  [HOST] [IPU2  ]    822.653327 s: [CAMERATASK]Front CAM(PCB ID 0) recover from reset!

Responses:
Hi, Could you explain what application you are running? Could you also describe more details about how the crash occurred? Does it always crash with the same error log? We never have any issue with MMU (for A15, M4, or DSP) on this device so I don't think you need to run any MMU test. Or, is the MMU unit you referring to something different than memory management unit? Regards, Stanley
